Column Address Circuit
Column Address Circuit has a 8-bit preset counter that provides Column Address to the Display Data RAM as shown
in figure 8. When set Column Address MSB / LSB instruction is issued, 7-bit [Y7:Y1] are set and lowest bit, Y0 is set
to “0”. Since this address is increased by 1 each a read or write data instruction, microprocessor can access the
display data continuously. However, the counter is not increased and locked if a non-existing address above 7EH. It
is unlocked if a column address is set again by set Column Address MSB / LSB instruction. And the column address
counter is independent of page address register.
ADC select instruction makes it possible to invert the relationship between the Column Address and the segment
outputs. It is necessary to rewrite the display data on built-in RAM after issuing ADC select instruction. Refer to the
following figure 7.

This circuit controls the display data by the display ON / OFF, reverse display ON / OFF and entire display ON / OFF
instructions without changing the data in the display data RAM.
